Summary
🤩
Rockstar🎓
Top SchoolMiguel Bernadin is a Tech Lead Site Reliability Engineer based in San Francisco with over a decade of hands-on experience designing and operating large-scale distributed systems. He has driven reliability, automation, and lifecycle ownership at high-growth companies including TikTok, Circle, BitMEX, and Pulze.ai, often leading migrations, CI/CD modernizations, and disaster-recovery improvements. Early work on DC/OS and contributions to the dcos/dcos project show a long-running focus on cloud-native installer, deployment and system-check automation across AWS and container ecosystems. Miguel combines engineering leadership with deep platform craftsmanship—implementing observability, networking (Calico→Cilium), and IAM/SCIM improvements—while keeping developer productivity and resilience front of mind. He’s equally comfortable writing low-level deployment fixes (shebangs, docker checks) and shaping team strategy to reduce toil and scale services. Known for pragmatic problem solving, he brings both operational rigor and a track record of shipping reproducible infrastructure at scale.
